I cloned a tic tac toe game repository to understand the logic of smart contracts and rust. It is working on moralis and need two player wallet addresses to play/create a game but when I add the second Phantom wallet ( both of them are my wallet but with different addresses) I am getting this error:

}

I can understand that the problem is related with my secret key size but I dont know how to fix it.

This error is possibly from this line of the code. It uses joined address strings of length 5 to create a unique secret for PDA account creation.

// Account Creation --- Start
const GAME_ACCOUNT_SECRET = `${player1.substring(0, 5)}${player2.substring(0, 5)}`;

Try updating it to this line by reducing the substring length to 4 or less.

const GAME_ACCOUNT_SECRET = `${player1.substring(0, 4)}${player2.substring(0, 4)}`;
